Appeal T-4076 - 1721 Martin Luther King Jr. Way, #3 - The tenants appeal a finding that there is insufficient evidence in the record to establish that the subject unit was rented in 1980. A review of the record establishes that there is conflicting information concerning the occupancy of the unit in 1980. The evidence is sufficient to support the hearing examiner's conclusion that the tenants failed to meet their burden of proving that their unit had been rented in May 1980. Also, because the owner acted on documents and information given to him by the Board when he set the tenants' rent in 1998, the doctrine of equitable estoppel precludes the Board from now reducing that rent. For these reasons, it is recommended that the decision of the hearing examiner be affirmed.
